A more thorough explanation:

Vis Expulsiva

Vis Expulsiva is a historical term that refers to the force used to expel or dispossess another.

During the medieval times, kings and lords used vis expulsiva to remove their enemies from their lands. They would use their armies to forcefully expel the opposing forces and take control of the territory.

In modern times, governments may use vis expulsiva to remove illegal immigrants from their country. They may use force to deport individuals who do not have the proper documentation to reside in the country.

These examples illustrate how vis expulsiva is used to forcefully remove someone from a place or position of power.
